Hi my girlfriend and I had unprotected sex last Wednesday night/ Thursday morning, we used the pull out method, and just a little bit went inside. Right I bought plan b, and she took it in less than an hour. She told me today that she hasn t had her period yet, but she should of had it by now. I spoke to 2 nurses and they told me that theres no way she can get pregnant. What is your opinion? Are we still ok, safe from having a baby?
